FERR'U'LE-CONTBACTING MACHINE.

Application flledeugust 8', 1922. Serial No. 579,510.

To all whom it may concern:

Be it known that I, CARL FREDERICK Wrcnmnn, a citizen of the United States of America, residing in borough of Brookl n,

a county of Kings, city and State of ew York, have inventedcertainnew and useful Improvements in Ferrule-Contracting Machines, of which the following is a specification. 4

This invention relates to ferrule contracting machines, and aims to provide certain improvements therein.

The invention is particularly directed to that type of machine in which by a move- 16 ment of the handle a plurality of jaws are brought forward to their inner or contracting position. The jaws may be restored to their outer or ferrule-receiving position by a reverse movement of the handle, or as in certain forms of such machines a complete movement of the handle from side to side may actuate the jaws inwardly, and then outwardly. v

The invention is applicable to such type :6 of machine, and provides a device having a minimum number of parts, which is strong anddurable, easilyconstructed, and cheap to manufacture.

' In the drawings, wherein I have shown the preferred form'of the invention,.

' Figure 1 is a side view, partly broken awa Fig. 2 is a diametrical section on the line --22mFig.1. y a I .35 Fig. 3 is a diametrical section on the line 33 m Fig. 1.

Fig. its a diametrical section on the line 44 in Fig. 1.

Referring to the drawings, I have shown 40 the machine as com rising a side plate A which may be provided with means for be ing fastened to'either a horizontal or vertical support, it being shown as havin a foot B to adapt it for resting upon. a ta le.

The side late A- is constructed with a Inrality of ugs C G, the outer sides of w 'ich are. curved at D to form a bearing .forthe movable member E. Preferably the lugs C are cast as a part of the side plate A, so that their outer peripheries may be machined on a 'lathein one operation. Each of the lugs is formed with straight sides F, the adjacent sides of each two lugs forming, a rectilinear guide for one of the dies G. There are preferably four of such dies, and their inner and working faces are suitabl configured in accordance with the work in hand. Ihe dies illustrated have faces which when contracted 0F BROOKLYN, NEW YORK, ASSIGNOR 1'0 A. SCHBA- I form a circle, thus adapting the machine for uniform contraction of the ferrule. The

'faces F of the lugs are so constructed that they can be machined diametrically completely across, thus facing either two or tour surfaces simultaneously. 1

The movable member E is adapted to be rotated in'the present instance through an are of about 45, and durin this movement.

is adapted to move the dies rom a full open position to a full closed position, and then again to a full open position. In this adaptation of the invention the device is open at the two extremes of its movement, and closed in its middle position, so that one stroke of the machine suflices to contract the ferrule, and reset it for the next operation. Y

The dies are moved by such rotativemovement by means of links H H, each of which" comprises a two-headed member, the heads.

being circular or substantially cylindrical in form, and the connecting part being of such width so that the member when viewed from its end resembles a dumb-bell in shape, the inner head working in a circular recess I in one of the dies and the outer head work- I ing in a circular recess J formed in the-rotative member. Preferabl the links are of the same thickness as the ies. The circular recesses are cheaply formed by the use of a drill press.

Another feature of the invention is the ease with which the dies may be assembledwhich best has a tapered periphery K, to

correspond with the taper E on the member E, and the retaining ring is best held in place by means of catch rods L, each of which has ahead L which passes through an elongated opening K in the retaining ring, and which may be turned across the opening, as illustrated in Fig. 1 to hold the retaining ring in place. The catch rods 'L preferably pass through to the opposite ice side of the side plate A, and are best provided with a fiat head M, by means of which the may be turned. A spring N ofwhieh are circular in form,

"ing their opposing normally olds the plates in'place, and thereby secures all of the parts in operative position. v

In assembling, the plate A is preferably laid on its side, with the rotative member in position, the .dies adjusted in position, and the links a plied,"whereupon the rods 'L- are pushed orward from the rear and sli ped through the openin K'l whereupon th y are turned. The devise. istthen ready for use. To assist in removing the maintaining ring, recesses 0 may be supplied in the faceof the rotative memberE.

To insure the proper positioning of the ring, pins P may be provided 0n opposite lugs which enter holes P in the ring.

I have shown the device as adapted for hand operation, in which case a suitable handle Q will be provided.

While I have shown and described one form of the invention, it will be understood that I do not-wish to be limited thereto, since various changes may be made therein without departing from the spirit of the invention.

What I claim is 1- i 1. A contracting machine comprising a side late having lugs the exterior surfaces of which are c1rcular in form, said lugs having their opposing faces constructed to form slideways, jaws in said slideways, a circular operating member fitting said exterior circular surfaces of the lugs and carrying members adapted to operate saidijaws,

said members being links formed with enlarged substantially cylindrical heads fitting into circular recesses in said operating member and jaws.

2. A contracting machine. comprising a side plate having gs the exterior surfaces ing laterally into said v machine comprising a f side plate having ugs the exterior surfaces of which are circular in form, said lugs havfaces constructed to form slideways, aws in said-slideways, acircular operating member fitting said exterior circ ular surfaces of the lugs and members adapted to operate said jaws, and operating member and jaws having circular recesses open toward each other and being laterally open, and double-headed links passt 3. A contract ing-their opposing faces constructed to form 'slideways, jaws 1n said slideways, a circular lags h I operating member fitting said exterior circular surfaces of the lugs and carryin members adapted to operate said jaws, an means for holding sald operating member in position, said means comprising springbolts having'heads adapted to be passed through elongated openings in said holding means and to be turned to secure the latter in place.'. a

4. A contracting machine, comprising a plate having 1 the exterior surfaces of "which are 0110 er, and a rotative member havin a bearmg on said circular faces, said lugs aving their opposing surfaces constructed to form slideways, radially movingdies in said slideways, and links connected with said rotative member and said dies, said dies and links constructed to be separated laterally, and a retaining ring for holding the parts together, said retaining ring being heldin position by spring rods having heads engaging the outer surface of In witness whereof, I have hereunto signed my name.

CARL FREDERICK WICHMANN.
